Test The Machine With This Thread And Needle Using Muslin.
Changing your needle corrects this. This can cause thread bunching underneath your fabric. When all upper threading is complete, be sure to slide the thread tension lever for thread guide c to the right, closing the holes in the thread guide.
Insert The Bobbin Into The Bobbin Case.
I have threaded and rethreaded upper machine and bobbin. Loops will appear on the bottom of the fabric if the upper tension is too loose. If your bobbin winder is not working, and this instruction comes from a repair of the ddl 8500, then it may have got stuck due to a lack of regularly oiling the machine.
My Bobbin Thread Keeps Looping And Tangling.
Verify that you are using the correct size bobbins.; Hold the bobbin in your hand with the thread hanging down on the right side. Close up of the flat head screw that adjusts the tension on the bobbin thread.
Always Thread The Sewing Machine With The Presser Foot Up.
Sometimes that's a good workaround for thread thickness. You will discover where the problem is occurring. Increase your needle tension by increasing the setting number with your knob, dial or button.
Pull Out A Few Inches Of Thread While You Are Holding The Bobbin Case In The Palm Of Your Hand.
Your needle thread is too loose. 1/8 to 1/4 of a turn (imagine a circle that is the head of the screw, only turn it 1/8 to 1/4 of the circle at a time). The sharp point of the needle catches the bobbin thread, which makes a loop.
